Patent attributes
A dynamic energy harvesting and variable harvesting force system is disclosed. A boost converter increases a motor voltage as a motor current associated with the motor voltage propagates through the boost converter thereby generating a boost voltage associated with the changing motor current. A power storage device stores energy harvested by the boost converter when the boost voltage exceeds an energy storage threshold. A controller dynamically adjusts a harvesting force applied by the motor so that the harvesting force is relative to the force applied to the motor. The controller also dynamically adjusts the harvested energy stored by the power storage device by adjusting the charging of the power storage device, ensuring that the boost voltage threshold is maintained. The boost voltage when maintained within the boost voltage threshold enables the power storage device to store the harvested energy without impacting the harvesting force applied by the motor.
